Rights Plan Policy

The Board shall seek and obtain stockholder approval before adopting a stockholder rights plan; provided, however, that the Board may determine to act on its own to adopt a stockholder rights plan without prior stockholder approval, if, under the circumstances, a majority of the independent directors, in the exercise of their fiduciary responsibilities, deem it to be in the best interests of Amgen’s stockholders to adopt a stockholder rights plan without the delay in adoption that would come from the time reasonably anticipated to seek stockholder approval. If the Board adopts a stockholder rights plan without prior stockholder approval, the Board will submit the stockholder rights plan to the stockholders for ratification, or the stockholder rights plan must expire, without being renewed or replaced, within one year. If submitted by the Board for stockholder approval, the plan will immediately terminate if not approved by a majority of the votes cast.

The Governance and Nominating Committee will review this policy statement on an annual basis, and report to the Board any recommendations it may have concerning the policy.
